is not for mechanical lifting.

3.05 Input Power Connections

The 50XL PLUS Power Supply(CE) accepts input volt-
ages of 220V ± 10% single or three phase, or 380/415V ±
10% three phase. Input can be 50 or 60 Hz. All units are
supplied with a six foot EMC input power cable.

A. Input Voltage Selection

The Power Supply is factory wired for 380/415V, three
phase input. For 220V input voltage, the Power Sup-
ply must be changed using the procedures in section
3.06. and 3.07.

B. Electrical Connections

The primary power source must conform to local elec-
tric code. Recommended circuit protection and wir-
ing requirements are shown in Appendix I).

C. Opening Power Supply Enclosure

The left side panel of the Power Supply must be re-
moved to gain access to the input voltage selection.

WARNING

Disconnect primary power at the source before as-
sembling or disassembling the Power Supply, torch
parts, or torch and leads assemblies.

1. Using a phillips head screw driver remove the top two

screws which secure the left side panel (viewed from
front of unit) to the frame assembly. Loosen the bot-

3.06 Input Voltage Selection

The Power Supply has two voltage settings: 220VAC or
380/415VAC. All 50XL PLUS Power Supplies are fac-
tory-wired for 380/415VAC. For 220VAC, the unit must
be reconfigured.

Input voltage selection is accomplished by switching a
wire harness connector inside the Power Supply.

Also for single-phase operation a jumper wire must be
properly installed (refer to Section 3.07, Primary Input
Power Cable Connections.)

WARNING

Disconnect primary power at the source before as-
sembling or disassembling the power supply.

To change the voltage selection move the power selec-
tion plug to the desired input connection for 220V or 380/
415V operation. Refer to the label attached to the panel.
